Q. The register used for indirect addressing of memory are called ____.
a) auxiliary registers (ARs)
b) block move address register (BMAR)
C) TREGn
d) index register (INDX)
Answers
Answer:
The register used for indirect addressing of memory are called index register (INDX)
Answer:
Concept:
This type of addressing involves including the address of the place where the target address is stored in the instruction. In this manner, the address of the target site is thereby indirectly stored in another memory location. Thus, the approach is known as indirect addressing. An indirect addressing method is one in which the address identifies the memory word or register that stores the operand's address rather than the operand itself. The same set of instructions can be repeated in the register indirect addressing mode. The register indirect addressing mode has more memory references than other modes.
Given:

Answer:
The answer is option (d) index register (INDX)
In a computer's CPU, an index register is a processor register or designated memory region used to change operand addresses while a programme is running. This worked well for doing vector/array operations and moving across fields in records during commercial data processing.
In a computer, an index register is a circuit that receives, holds, and outputs codes that change the instructions. An address register or a record of modifications are other names for this circuit. A register is a location in a computer processor where data is stored. In the index addressing mode, the index register's contents are added to the instruction's address portion to produce the effective address. The base, or starting address, is contained in the instruction's address section. The index value, +ve, is stored in the index register.
A method of creating an effective address that alters the specified address provided in the instructions by the content of a specified index register is known as indexed addressing (indexing). Typically, the update is adding the contents of the index register to the given address.
